The aim of this study was to compare (a) two different umbilical cord blood (UCB) collection methods while the placenta is still in the uterus (in utero), and (b) to evaluate the efficacy of four cryopreservation protocols based on UCB haematopoiestic stem cell (HSC) recovery. We analysed UCB samples collected with our original collection system designed(More)
The efficiency of five different cryopreservation protocols (our original controlled-rate and noncontrolled-rate protocols) was evaluated on the basis of the recovery after thawing of very primitive pluripotent hemopoietic stem cells (MRA(CFU-GM), pluripotent progenitors (CFU-Sd12) and committed granulocyte-monocyte progenitors (CFU-GM) in mouse bone(More)
Acetylsalicilyc acid (aspirin, ASA) is a well known anti-inflammatory drug with immunomodulatory properties. NO-releasing aspirins (NO-ASA) are new compounds with anti-inflammatory properties. We studied the effects of ASA and two NO-ASA (NCX 4016 and NCX 4040) on human monocyte-derived dendritic cells (MoDC). Immature MoDC were generated in vitro from(More)
Advancement in the field of nanotechnology and its applications to the field of medicines and pharmaceuticals has revolutionized the twentieth century. Nanotechnology [1] is the study of extremely small structures. The prefix “nano” is a Greek word which means “dwarf ”. The word “nano” means very small or miniature size. Nanotechnology is the treatment of(More)
Several laboratories have developed culture systems that allow the generation of large numbers of human dendritic cells (DC) from monocytes using granulocyte-macrophage colony stimulating factor (GM-CSF), and interleukin-4 (IL-4). In this work we provided evidence that GM-CSF (100 ng/ml) in combination with a low concentration of IL-4 (5 ng/ml) was(More)
This report presents our experience with cytaphereses performed in treatment of 476 patients. Leukapheresis was used in management of 68 patients with hyperleukocytosis leukostasis (WBC > or = 150 x 10(9)L(-1)). Average decrease in cell count after treatment was 73.3%. Plateletapheresis for 32 patients (platelets > or = 1500 x 10(9)L(-1)) was applied in(More)
Angiogenesis in solid tumors is important for tumor growth, invasion, and metastasis. However, angiogenesis plays also an important role in hematological malignancies. We have analyzed the expression of vascular endothelial growth factor (VEGF) in the leukemic blast cells and microvessel density (MVD) in the bone marrow biopsy samples of the patients with(More)
BACKGROUND Experimental and first clinical studies suggest that the transplantation of bone marrow derived, or circulating blood progenitor cells, may beneficially affect postinfarction remodelling processes after acute myocardial infarction. AIM This pilot trial reports investigation of safety and feasibility of autologous bone marrow-derived progenitor(More)
BACKGROUND AND METHODS The aim of the study was to evaluate retrospectively clinical course of 27 patients with primary central nervous system lymphoma (PCNSL) diagnosed and treated by different surgical approaches. Initial therapy-diagnostic approach included surgery with total tumour reduction (TTR) performed in 12 patients (44.4%), while partial(More)
